993 goes into 21 0 times with a remainder of 21.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 21 after subtracting 0 from 21.
Bring next digit (7) of the dividend behind the 21 and repeat the process: 217 / 993

Advancing to step 3:
The number 993 fits into 217 0 times, leaving a remainder of 217.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 217 and we're left with 217.

Going ahead to step 4:
2173 divided by 993 is 2 with a remainder of 187.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Subtract 1986 from 2173 to get 187.
Grab the next digit (9) from the dividend, add it to 187, then carry on: 1879 / 993

On to step 5:
993 can be fit into 1879 1 times, resulting in a remainder of 886.
The number 1 becomes the next digit in our result. 
Result so far: 21.0
Deduct 993 from 1879 and we're left with 886.
Grab the next digit (2) from the dividend, add it to 886, then carry on: 8862 / 993

Advancing to step 6:
993 goes into 8862 8 times with a remainder of 918.
Write down 8 as next digit of the result. 
Result so far: 218.0
If we subtract 7944 from 8862, we get 918.
Append the next digit (5) from the dividend to 918 and continue with: 9185 / 993

Step 7:
9185 divided by 993 is 9 with a remainder of 248.
Record the quotient 9 as the next digit in the result. 
Result so far: 2189.0
Subtract 8937 from 9185 to get 248.
Bring next digit (4) of the dividend behind the 248 and repeat the process: 2484 / 993

Going ahead to step 8:
When dividing 2484 by 993, we get 2 with a remainder of 498.
The number 2 becomes the next digit in our result. 
Result so far: 21892.0
Subtracting 1986 from 2484 leaves us with 498.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4980, and continue the process.

Going ahead to step 9:
If we divide 4980 by 993, we get 5 and a remainder of 15.
Write down 5 as next digit of the result. 
Result so far: 21892.5
Deduct 4965 from 4980 and we're left with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Moving on to step 10:
When dividing 150 by 993, we get 0 with a remainder of 150.
Write down 0 as next digit of the result. 
Result so far: 21892.5
Subtract 0 from 150 to get 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Step 11:
993 can be fit into 1500 1 times, resulting in a remainder of 507.
The number 1 becomes the next digit in our result. 
Result so far: 21892.501
Deduct 993 from 1500 and we're left with 507.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5070, and continue the process.

Moving on to step 12:
5070 divided by 993 is 5 with a remainder of 105.
Put 5 as the next digit of the answer. 
Result so far: 21892.5015
Deduct 4965 from 5070 and we're left with 105.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1050, and continue the process.

Step 13:
993 goes into 1050 1 times with a remainder of 57.
Use 1 as the next digit of our solution. 
Result so far: 21892.50151
Deduct 993 from 1050 and we're left with 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Moving on to step 14:
If we divide 570 by 993, we get 0 and a remainder of 570.
Put 0 as the next digit of the answer. 
Result so far: 21892.50151
If we subtract 0 from 570, we get 570.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5700, and continue the process.

Going ahead to step 15:
If we divide 5700 by 993, we get 5 and a remainder of 735.
Record the quotient 5 as the next digit in the result. 
Result so far: 21892.5015105
Subtract 4965 from 5700 to get 735.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7350, and continue the process.

Moving on to step 16:
993 can be fit into 7350 7 times, resulting in a remainder of 399.
Use 7 as the next digit of our solution. 
Result so far: 21892.50151057
Deduct 6951 from 7350 and we're left with 399.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3990, and continue the process.

After the division, we end up with 21892.50151057 and a remainder of 3.99e-07.
